Fraxinus spp. logs infested with Agrilus planipennis Fairmaire (Coleoptera: Buprestidae) were fumigated with sulfuryl fluoride (SF) in 432-liter chambers at 15.6 and 21.1 degrees C for 24 and 48 h. Concentration x time (CxT) exposures (g-h/m3) of SF obtained were 3,382 (24-h exposure) and 5,466 (48-h exposure) at 15.6 degrees C and 3,329 (24 h) and 4,385 (48-h exposure) at 21.1 degrees C after doses of 144, 128, 128, and 104 g/m3, respectively. After aeration, logs were placed in modified fiber drums for 8 wk to capture emerging beetles. No adults emerged from any of the fumigated logs, whereas 933 adults emerged from control logs. Eggs were fumigated at CxT exposures similar to log fumigations (3,240 and 4,262 g-h/m3, respectively) and again at doses 16 g/m3 lower, at 21.1 degrees C for 24 and 48 h. No hatch was observed at CxT dosages > 4,262 g-h/m3. No larvae continued development on artificial diet after hatching from eggs fumigated at all tested dosages, whereas 10 control larvae developed to instar I or II. Chamber fumigations with 31 and 46% load factors provided additional sorption and concentration data. A. planipennis-infested logs in tarped, 149.1-m3 cargo containers were fumigated at dosages used in successful trials. Logs were monitored for 8 wk for adult emergence. There was no adult emergence, but 621 adults emerged from a similar quantity of control logs. CxT dosages of SF for 100% control of A. planipennis at 15.6 and 21.1 degrees C for 24- and 48-h exposure can be obtained under commercial fumigation conditions. A quarantine treatment schedule for SF is proposed.
被 Agrilus planipennis Fairmaire（鞘翅目：扁甲科）寄生的 Fraxinus spp.原木在 15.6 和 21.1°C 的 432 升室中用二氧化硫氟（SF）熏蒸 24 和 48 小时。在 15.6°C 下，SF 的浓度 x 时间（CxT）暴露量（g-h/m3）分别为 3382（24 小时暴露）和 5466（48 小时暴露），在 21.1°C 下，剂量分别为 144、128、128 和 104 g/m3 时，暴露量分别为 3329（24 小时）和 4385（48 小时）。熏蒸后，原木被放置在改良纤维桶中 8 周以捕获新出现的甲虫。没有成虫从任何熏蒸过的原木中出现，而对照原木中有 933 只成虫出现。卵在与原木熏蒸相似的 CxT 暴露下被熏蒸（分别为 3240 和 4262 g-h/m3），然后在剂量降低 16 g/m3 的情况下再次熏蒸，在 21.1°C 下熏蒸 24 和 48 小时。在 CxT 剂量>4262 g-h/m3 时，未观察到孵化。在所有测试剂量下熏蒸的卵孵化后，没有幼虫在人工饲料中继续发育，但 10 只对照幼虫发育到 1 龄或 2 龄。用 31%和 46%负载因子进行的舱室熏蒸提供了额外的吸附和浓缩数据。在有篷的 149.1 立方米货物集装箱中，用在成功试验中使用的剂量对被 Agrilus planipennis Fairmaire 感染的原木进行熏蒸。原木在 8 周内监测成虫的出现情况。没有成虫出现，但从类似数量的对照原木中出现了 621 只成虫。在 15.6 和 21.1°C 下，24 小时和 48 小时暴露，SF 的 CxT 剂量可获得 100%控制 Agrilus planipennis Fairmaire 的效果，用于商业熏蒸条件。提出了 SF 的检疫处理时间表。
